IMPROVEMENT IN VESSELS FOR MIXING LIQIJID COMPOUNDS.

Specification forming part of Letters Patent No. 219,349, dated September 9, 1879 application filed February 14, 1879-.

To all whom it may concern:

Be it known that I, 0'r'ro DIERKING, of the city of Brooklyn, in the county of. Kings and State of New York, have invented a new and useful Improvement in Vessels for Mixing Liquid Compounds, of which the following is a specification.

The invention consists in the combination of a transparent receiving -vessel provided with gage-marks denoting quantity with a I tightly-fitting metallic cap or cover constructed with a strainer and vent-hole capable of being opened and closed by the operation of a stop-key.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is a perspective of a device embodying my invention. Fig. 2 is a view of the metallic cap or cover, with the strainer, venthole, and stopkey therewith connected.

Referring to said drawings, A is the transparent receiving-vessel, having an engraved vertical line, a, through its entire length, from which the gage-marks b b I) I) extend at right angles, being numbered, respectively, 1 2 3 4 at their terminal points.

It is obvious that these gage-marks may be indicated in various ways and extended indefinitely.

B is the metallic cap or cover, having a strainer, G, in the form of a lip, the inner face whereof is perforated in a suitable manner. d

is a vent-hole at or near the center of the cover, and e is the stop-key, which is held open by its own spring, and which, upon being pressed downward, closes both the venthole and the strainer against leakage.

The operation of the device is as follows: The liquid ingredients to be mixed and combined are first poured into the receiving-vessel A, the cover B is then applied, and the stopkey 0 pressed down upon the vent-hole and strainer. The ingredients are then thoroughly mixed by agitation, after which they are poured off through the strainer.

This device admits of the use of a single receiving-vessel, and insures correct proportions in the mixture of liquids, which old methods do not provide for.

I claim as my invention The combination of a transparent receivin g-vessel provided with gage-marks with a ti ghtly-fitting cap or cover constructed with a strainer and vent-hole, and having a stop-key held open by a spring when not under pressure, constructed and operated substantially as and for the purposes herein described.

OTTO DIERKING.
